It is necessary to determine experimentally the standard welding parameters before beginning the welding. However, the social loss of such experiments, which may be repeated in each work and in each case, is not small. If the relationship among the welding parameters may be computerized and the standard welding parameters may be available by computer, the material, labor and time losses will be saved. This study is to make an algorithm for computerizing welding parameters. At first step the

... rithm for submerged arc welding proposed by Richter et al. was modified and experimentally studied. In conclusion, the algorithm for submerged arc I-butt one pass welding is proposed under the condition that a calculated penetration depth (PC) is from 0 to 1 mm less than the plate thickness.
